Earthquake Freqs??

[judas12]

Are their any earthquake freqs in our area ?

Well...my pager will vibrate when it hears 154.1900mhz. Does that count?
Sorry,I had to go there,lol!

Maybe u need to stay in your own forum and have ignorant answers for the good ol boys in your town, village, tents, or wherever u live. The funny part is that u still have a pager. Cant mommy afford to buy u a cell phone???? Oh i forgot, you're from the midwest. LOL!! SORRY , I HAD TO GO THERE

[gewecke]

Nope,my department bought it for me. Sorry,didn't mean to offend you. My humor is a bit out there sometimes! I saw the opportunity to make a funny and ran with it.
Again,no offense intended.

I know years ago, there used to be the "Seismic Precursor Net" on 146.940. It was a ham group that was active in monitoring earthquake activity. Don't know if they're still around or not. They even had the freq's that monitored the water level in wells dug along the San Andreas fault. Quite a good group actually. Got my ham ticket because of them.

this is why weed should be legal

Cool, thanx bro i'll try it out and see if it works

I like WEED, though it does get a bit confusing trying to concentrate on dispatchers when im stoned, but oh well.

This is cool,because we have a local rptr. on 146.940 with a pl of 103.5 It's the W9AML repeater in bloomington Ill. There's a lot of shaky people on there,lol!

That's kind of a broad question and I am not sure I understand what you're looking for. However, I show the following 3 amateur radio frequencies used during earthquakes in southern California:

144.3450 S CA Earthquake Ham Radio Net a
147.3050 S CA Earthquake Ham Radio Net b
147.7050 S CA Earthquake Ham Radio Net c

There are some high frequency sensors that monitor vibrations up in the mountains, near Los Gatos; where there was a big earthquake almost 20 years ago. Go wandering into the Forest of Nisene Marks off of Highway 1. You'll find the fissures (cracks) and pick up the transmitters on a dummy load antenna...

There is one I'm familiar with on 163.795 MHz in SoCal.

I found this info on it:
Some earthquake seismometers broadcast the magnitude of the earth’s displacement via radio. The tone on the carrier changes in direct proportion to the displacement of the seismometer. So with a radioseismometer you can hear an earthquake coming...or hear the earthquake waves in the Earth generated by far away earthquakes like in China, Japan, or Chile. The primary seismometer that can be heard in Orange County is the San Sevaine seismometer located on the San Sevaine flats (near Lytle Creek) in the San Gabriel Mts. The San Sevaine seismometer broadcasts its carrier on 163.795 MHz. This seismometer is a little hard to hear in OC, so you will need an antenna with some gain over a ¼-wave vertical or whip antenna.

Most of the time after feeling the shaking of an earthquake, ham radio operators will get on the air to begin their part in assessing if the quake is a major event. Best to plug in that bunch of ham radio frequencies that are in your area, on the 6 and 2 meters, along with those on the 440, 220, 900 and 1.2 frequencies.

You might want to look up the USGS (Geological Survey - Menlo Park) freqs in the federal database. The remote data gathering sites use solar power and are uploaded to satelites using microwave frequencies.

Or, if your into Twitter, you might be able to EQ info faster still - maybe?

Do you know if that one is still active?

I used to listen to some of these but lost the signals. Learned about them through the Seismic Precursor Net mentioned by Lt51506. Dick La Belle, W6FXN used to host that net. I used to monitor a seismometer 24/7, filtering the tone through a notch filter. You'd only really hear it when the pitch went above or below the center freq. Had it on while living in Lake Forest when the Northridge quake struck. It woke me up at least 10 seconds before the shaking reached me. Just sitting there in the dark, waiting for it, not knowing where it was or how big it was going to be. Then the aftershocks... The seismometer would go to the rails even for smaller quakes, so you just didn't know if you would feel it until it arrived. But a big one had an unmistakable signature to it. And a large, overseas quake had a slow rise and fall tone. It sounded just like a seismogram printout looks.

Yes, it is transmitting at this time.

[RadioDaze]

Thank you. I'll program it in and see if I can pick it up. I've had the feeling we're all due for a big one soon.
